mysql8安裝后如何修改root密碼

mysql5.7.9之后，就沒有了password函數，所以，使用傳統的password()函數修改root密碼的話，就會提示sql錯誤

 

 UPDATE user SET authentication_string = password('123456') WHERE User='root';

ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '('123456') WHERE User='root'' at line 1

 

 

正確設置密碼的方法是：

ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY '123456';

此時提示修改成功，退出mysql再次登陸即需要輸入剛剛設置的密碼。
